`$*' is something entirely different, yes. I've written a lengthy page
in zsh's wiki that explains some of the subtle differences between $*
and $@, double-quoted or not.

"$@" (the quoted form) however is rock solid. And also very
idiomatic. So idiomatic in fact that there's a short hand:

  % for i in "$@"; do ...; done

and

  % for i; do ...; done

are the same.

Also, while-shift is destructive with respect to $@. for-"$@" is not.

Regards, Frank
